But the North Atlantic Treaty regulating NATO does not have an option to suspend or even expel members. But there's the possibility to do something to the same effect when a member state persistently violates the principles contained in the pact—by failing to safeguard the freedom of its people, the country's democracy and the rule of law. In that case, NATO members can unanimously decide to stop assisting that ally.

Was there any talk or initiative made to introduce a formal process for suspending or terminating membership from NATO? The article discuss whether a country like Turkey can be kicked from NATO, and mentions that yes it is possible for a country to be de-facto expelled, but that there's no formal process for doing so, so I was wondering if there was any talk or initiative made to solve that issue.
